All contest submissions are due by 7:00 PM local time in the eastern time zone of the United States on the last day of every other month. Because of Daylight Saving Time, this is GMT-4 on April 30th, June 30th, August 31st, and October 31st, and GMT-5 on December 31st and February 28th/29th.

Any late submissions entered before the compilation is created might be included, but there is no guarantee of this, so please get your entry in on time. Entries that miss the cut-off will be entered into the next contest period. If, for any reason, the contest deadline is extended, an announcement will be made announcing the extension. The deadline will never be cut short.
